When someone says "exoskeleton," it's easy to imagine a clunky contraption made of metal, like the one we typically see in the news courtesy of various research groups, or in movies like Edge of Tomorrow. The exoskeleton that Harvard's Wyss Institute is developing, though, doesn't look like it was torn off a robot: it's called the Soft Exosuit, and as its name implies, it's lightweight and made of fabric. Wyss has actually been working on the Soft Exosuit for years, but now DARPA has granted it a $2.9 million funding under its Warrior Web program to further its development. Its current iteration is really more like smart clothing that can be worn like pants, designed to mimic how leg muscles and tendons move and to support the users' joints as they walk. That's made possible thanks to the strategically placed straps around the legs that contain flexible sensors -- all controlled by a low-power microprocessor.
